BUILDING-TILE.

Specification of Letters Patent.

Patented Oct. 26, 1920.

Application filed December 5, 1918. Serial No. 265,399.

Illinois, have invented certain new and use-' ful Improvements inBuilding Tiles,'0f

which the following is a description.

My invention applies more particularly to tiles constructed of gypsumproducts adapted for use in roof construction. It has for its object theconstruction of a tile for the purpose stated which shall possesssufficient strength to reliably perform the functions required, andwhich shall provide more reliable means for the engagement and supportof the contiguous tiles going to make up such a roof.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out same being partly in section to showtheconstruction;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a cross section on line 44 of Fig. 1; a

Fig. 5 is a top plan view of one of my improved tiles;

Fig. 6 is a bottom plan view of the same;

Fig. 7 isan edge view of the same; and

Fig. 8 is an endview taken from the right of Fig. 7. i

In the drawings, 1 represents a tile preferably formed from gypsumproducts and recessed on the bottom faces as at 2 in Figs. 4 and 6. Thetile is preferably strengthened by suitable reinforcing means, forillustration by reinforcing rods 3 longitudinally extending through thedepending edges of the tile below the medial plane, and at the ends bentupward and backward as at 4 to firmly lock the ends of the reinforcingrod in place. The tile upon its-upper surface, along either one or bothedges of the same, is recessed as at 5 for the purpose of filling 'in asuitable cement when the tile are laid in place, to. serve to fill thecrack and tend to make the roof water tight. The nature'- of the cementmay also tend to unite the tile into a homogeneous mass. The ends of thetile are similarly constructed to receive a closing cement as at 7.

The tile when formed into a roof are preferably supported near the endsby suitable transverse metal beams 8, rendering the roof fire proof. Inactual practice it is found that metal beams of the character shownfrequently warp in rolling, so that in some instances the ends ofmeeting tiles do not rest equally upon the upper surface of the beam.For the purpose of providing adequate and effectual support for the endsof both the meeting tiles and to make an improved connection betweenthem, I form the body of my tile near the upper and lower surfaces so asto extend longitudinally in opposite directions as at 9, 10. Preferablynear the medial plane of the tile is provided a supporting ledge 11 onthe extension 10, extending substantially parallel to the upper surfaceof the tile. On the cooperating part of the end 9 a mating part 12 ispro vided so that the end 10,'firmly resting upon the beam 8, insures asupport for the end 9 of the contiguous tile.

Since articles of this character are liable to chip, it is desirablethat acute or right angles should be avoided as far as possible in themeeting ends of the tiles, and to accomplish this, as clearly shown inFig. 3, the vertical faces 13, 14 respectively are connected to theledge 11 and the cooperating part 12 by inclined or obtuse faces 15, 16respectively. It will thus be seen that the meeting ends of thecontiguous tiles are mating, and that one of the tiles aids in thesupport of the meeting end of the contiguous tile. In practice it hasbeen found that even in cases where the beam 8 is warped to such anextent that the tile at the right, shown in Fig. 3, has very slight, ifany, bearing upon the beam, the support of the mating tile is foundsufficient for the purposes of the roof construction.

It is obvious that the particular configuration of the mating ends maybe modified to a considerable extent without departing from the spiritof my invention, the main object and purpose being to provide a tile ofsuflicient strength for the purpose and supply adequate auxiliarysupport to the overlapping tile' over and above the sup ort that may besecured upon the beam 8. lsothat the meeting edges of the upper surfacemay be united with a suitable cement.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without dearting fromthe spirit of my invention; iience I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentionedexcept in so far as I may be limited by the scope of the appendedclaims.

What I claim as new and desire to secure by Letters Patent is:

1. A building tile comprising a main body part provided with endextensions near its upper and lower surfaces to constitute meetingsupporting ends of contiguous tiles at one end, and reinforcing rodsextending longitudinally of the tile to one side of and parallel withthe medial plane of the tile, and having end portions extending into thesaid end extensions, thence transversely of the tile, and thenbackwardly and longitudinally into the main body part of the tile.

2. A building tile constructed with the body near the upper and lowersurfaces longitudinally extended in opposite directions to constitutemeeting supporting ends of contiguous tiles at one end, each end portionof each tile having a longitudinally extending face portion, a verticalface portion at each side of and extending at right angles to thelongitudinally extending face portion, and inclined face portionsbetween the longitudinally extending face portion and the vertical faceportions.

3. A building tile constructed with the body near the upper and lowersurfaces lon= gitudinally extended in opposite directions to constitutemeeting supporting ends of contiguous tiles at one end, each end portionof each tile having a longitudinally extending face portion, a verticalface portion at each side of and extending at right angles to thelongitudinally extending face portion, and inclined face portionsbetween the longitudinally extending face portion and the vertical faceportions, and reinforcing rods extending longitudinally to one side ofthe medial plane of the tile into the said end extensions of the tileand thence extending vertically of the tile adjacent to and parallelwith the inclined face portions of the end extensions of the tile topoints above the medial plane of the tile.

4:. A building tile comprising a main body part provided with endextensions near its upper and lower surfaces to constitute meetingsupporting ends of contiguous tiles at one end, and reinforcing rodsextending longitudinally of the tile to one side of and parallel withthe medial plane of the tile, and having end portions extending into thesaid end extensions, thence transversely of the tile, and thenbackwardly and longitudinally into the main body part of the tile to theopposite side of the medial plane thereof.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
